Trimaran
A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs. Terminology The word "trimaran" is a portmanteau of "tri" and "(cata)maran", a term that is thought to have been coined by Victor Tchetchet, a pioneering, Ukrainian-born modern multihull designer. Trimarans consist of a main hull connected to outrigger floats on either side by a crossbeam, wing, or other form of superstructure—the traditional Polynesian terms f ...

Multihull
A multihull is a boat or ship with more than one hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans (with two hulls), and trimarans (with three hulls). There are other types, with four or more hulls, but such examples are very rare and tend to be specialised for particular functions. Sailing multihulls Counter-intuitively, it is unhelpful to think of the design progression to be "1-2-3", namely monohull - catamaran - trimaran; rather, it is "1-3-2". A sailing trimaran is, in effect, a modified monohull with lightweight outrigger hulls (or "amas") for stability instead of a heavy deep keel; so it follows that a sailing trimaran will be lighter and faster than a sailing monohull. A sailing trimaran will have a centre hull that may comprise up to 90% of total hull volume, and 95% of total deadweight. A sailing trimaran at rest will have both amas out of the water and, when heeled, will only ever have one of the amas immersed. A ...

Victor Tchetchet
Victor Tchetchet (June 19, 1891 – April 26, 1974) was a pioneering early modern multihull sailboat designer from Ukraine (at his birth part of the Russian Empire) who is thought to have coined the term 'trimaran', though Éric de Bisschop built a trimaran in France earlier. He was also a landscape and portrait painter. Born in Kyiv, Victor was inspired by South Pacific outriggers to connect two canoes to make a catamaran and enter the Kyiv Imperial Yacht Club's local races. After winning, he was disqualified. In 1923 Tchetchet emigrated to New York City and further experimented with catamarans and trimarans. In 1945 he launched his first trimaran, of length. Tchetchet entered the Marblehead Race Week in 1946. Despite a poor performance, his participation helped to overcome the local prejudice against multihulls after Nathanael Herreshoff's 1876 win with the catamaran ''Amaryllis'' at the New York Yacht Club's Centennial Regatta. In the same year, he established the Inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing ve ...

Vaka (sailing)
Polynesian multihull terminology, such as "ama", "aka" and "vaka" (or "waka") are multihull terms that have been widely adopted beyond the South Pacific where these terms originated. This Polynesian terminology is in common use in the Americas and the Pacific but is almost unknown in Europe, where the Anglo-Saxon terms "hull" and "outrigger" form normal parlance. Outriggers, catamarans, and outrigger boats are a common heritage of all Austronesian peoples and predate the Micronesian and Polynesian expansion into the Pacific. They are also the dominant forms of traditional ships in Island Southeast Asian and Malagasy Austronesian cultures, where local terms are used. Etymology The term ''vaka'' or ''waka'' means "boat" or "canoe" in most Polynesian languages. It comes from Proto-Austronesian *abaŋ , meaning "ship" or "canoe". Cognates in other Austronesian languages include Ivatan language, Ivatan ''Awang'', Tagalog language, Tagalog and Visayan languages, Visayan ''bangka'', M ...

Single-outrigger
Outrigger boats are various watercraft featuring one or more lateral support floats known as outriggers, which are fastened to one or both sides of the main hull. They can range from small dugout canoes to large plank-built vessels. Outrigger boats can also vary in their configuration, from the ancestral double-hull configuration (catamarans), to single-outrigger vessels prevalent in the Pacific Islands and Madagascar, to the double-outrigger vessels (trimarans) prevalent in Island Southeast Asia. They are traditionally fitted with Austronesian sails, like the crab claw sails and tanja sails, but in modern times are often fitted with petrol engines. Unlike a single-hulled vessel, an outrigger or double-hull vessel generates stability as a result of the distance between its hulls rather than due to the shape of each individual hull. As such, the hulls of outrigger or double-hull boats are typically longer, narrower and more hydrodynamically efficient than those of single-hul ...

Sailboat
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture. Types Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan. Popular monohull designs include: Cutter The cutter is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for a jib and staysail to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds.

Austronesian Peoples
The Austronesian peoples, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples in Taiwan, Maritime Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia. Based on the current scientific consensus, they originated from a prehistoric seaborne migration, known as the Austronesian expansion, from pre- Han Taiwan, at around 1500 to 1000 BCE. Austronesians reached the northernmost Philippines, specifically the Batanes Islands, by around 2200 BCE. Austronesians used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, lashed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yacht Of Boracay
A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are: —carrying no more than 12 passengers, —solely for the pleasure of the owner and guests, or by Flag#At sea, flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than . Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020 there were more than 15,000 yachts of sufficient size to require a professional crew ...
